fix(cli): fix prompt issue in mcp configure claude-code (#17599)
* Updates default Coder prompt. * Skips the directions to report tasks if the pre-requisites are not available (agent token and app slug). * Adds the capability to override the default Coder prompt via `CODER_MCP_CLAUDE_CODER_PROMPT`.
